Polysexuality (not be confused with polyamory) is a sexual orientation related to bisexuality and pansexuality. While bisexuality is defined as being attracted to both men and women, and pansexuality is defined as being attracted to all genders (including non-binary ones)[note 1], polysexuality is defined as being attracted to more than one gender and/or form of gender expression, but not all.

A polysexual, might, for example, be attracted to femininity, and thus find themselves attracted to women (both cis and trans), afab people who are feminine, and amab people who are feminine, regardless of the gender identity of the last two. However, as the polysexual in our example is not attracted to most men, it would be a misnomer to call them a bisexual or a pansexual. This particular polysexual person could be called "femmephilic", as they are attracted to femininity, but the attraction is not limited to women.

A polysexual may find themselves attracted to men, women, and bigender people and find themself completely unattracted to other non-binary gender identities.

Or a polysexual may find themselves attracted to women and agender people, but no other genders.

Bear in mind these are merely examples. Other polysexual people may experience their attractions completely differently.
